Tusk SolidGrey3000 is the world’s first Stereolithography material that combines a high degree of stiffness with high impact resistance, and it is available exclusively at Materialise. Parts built with this material are not only robust, but highly functional as well, allowing them to be used in a wide variety of applications. Ideal applications include automotive body parts, machine covers, functional prototypes, durable concept models and robust scale models.

Technical Specifications

Standard lead time

Minimum of 3 working days , depending on part size, number of components and finishing degrees

Standard accuracy

± 0.2% (with lower limit on ± 0.2 mm)

Minimum wall thickness

0.8 mm

Layer thickness

0.1 mm

Maximum part dimensions

The maximum build envelope is 2100 x 700 x 800 mm

Surface structure

Unfinished parts typically have visible building layers on the surface but post-production finishes can achieve different effects, from high glosses to coarse textures. Stereolithography parts can be sandblasted, smoothed, colored/impregnated, painted, varnished, covered and coated.

How Does Stereolithography Work?

Stereolithography is a laser-based technology that uses a UV-sensitive liquid resin. A UV laser beam scans the surface of the resin and selectively hardens the material corresponding to a cross section of the product, building the 3D part from the bottom to the top. The required supports for overhangs and cavities are automatically generated, and later manually removed.
